Solve using a system of three linear equations.A real estate investor is examining a triangular plot of land. She measures each angle of the field. The sum of the first and second angles is 60° more than the measure of the third angle. If the measure of the third angle is subtracted from the measure of the second angle, the result is twice the measure of the first angle. Find the measure of each angle. (Note: The sum of the angles of a triangle is 180°.)

Question

A. First angle is 24°, second angle is 102°, third angle is 54°
B. First angle is 18°, second angle is 100°, third angle is 58°
C. First angle is 20°, second angle is 100°, third angle is 60°
D. First angle is 26°, second angle is 96°, third angle is 58°

Answer 1

Answer: C
